2. Wash both the clutches and the belt in hot soapy water
Not only should the clutches be cleaned with hot soapy water, but the belt should as well. When belts are manufactured, they use mold release to help the belt come out of the mold easier. This mold release usually leaves a residue on the belt which can cause belt slippage. Cleaning the belt with a soft bristle brush in hot soapy water and then rinsing will reduce the chance of slippage with a new belt.
3. Check and adjust factory center-to-center and clutch alignment
Quite often clutch alignment or center-to-center measurements can vary from what the OEM specifies, even on a new unit. This can hinder clutch efficiency and cause pre-mature belt wear or failure. The factory service manual lists the measurement specifications for each model and the procedure for proper measurement. If one of these measurements is not correct, the motor mounts may need to be loosened so the motor can be arranged to bring these measurements back into specification. In some extreme cases, the motor mount plate or straps may need to be notched or slotted to allow enough movement to achieve proper alignment or center-to-center distance.
4. Adjust for proper belt-to-sheave clearance
